ES2268908T3 - PROCEDURE TO ENCAMINATE MESSAGES IN AT LEAST A TELECOMMUNICATIONS NETWORK ACCORDING TO THE GSM STANDARD. - Google Patents

Abstract

A Network Address Register (NAR) is a routing device for use in a GSM telephone system. The NAR receives network messages and determines the network address of the appropriate network elements (network items) that is the destination of the message. The NAR allows subscribers and network elements of the GSM telephone system to be assigned independently. Existing methods of assigning subscribers and network elements using fixed association, such as telephone number blocks, are eliminated.

Description

Procedure to route messages in al less a telecommunications network according to the GSM standard.

Countryside

The invention relates to a method for route messages in at least one telecommunications network according to the GSM standard with one or more network elements with specific data of the user.

State of the art

In GSM mobile radiotelephony networks, the data of user for the mobile phone user are kept in a central database, the home position registry home Location Register "(HLM). As the number of users and, with it, the growing need for phone numbers, the relationships between HLR designs, SIM cards and WMSC through the necessary block building of phone numbers and their distribution in the HLR and VMSC become considerably complex. The design principle hindered by the number of desired phone, taking into account the construction of blocks for MSISDN and IMSI, is due to the increasing complexity with performance limits Due to capacity limits conditioned by the systems technique of an HLR, in the networks of mobile radiotelephony with a large number of users there are generally more than one HLR to record the data of all users The establishment of in which HLR the set is deposited respective user data is determined with the help of numbers Telephone number of mobile radiotelephony users (RSDI number of the mobile station, MSISDN) or its IMSI (the establishment must affect only the network start).

In addition to the HLR there are other network elements that contain user-specific data, such as, for example, Service Control Points (SCP) with integrated service data function "Service Data Function "(SDF) in the intelligent network (RI) or the center of Voice Mail Service Center (VMSC) as a central answering machine in the switching network.

Since all HLRs are stored in the HLR GSM user data and a user is identified through their MSISDN (for example by MTC) or through your IMSI (for example, by position update "Location update"), the MSC / VLR for example you should be able to determine the user's HLR with the help of MSISDN or IMSI. Due to capacity limits and administration can not deposit all phone numbers individual and IMSI in the MSC routing table. Therefore it define blocks, as mentioned, that are associated each to a given HLR and for which the routing is correspondingly configured in the MSC. Since in the SIM cards are programmed the individual IMSI of each user, the SIM card / phone number combination must match in the moment of activation of the user and associate to the same HLR. If this this is not the case, the so-called virtual user entries arise in the HLR, for which only one capacity is available limited

An estimate of the foreseeable development of the distribution of users in the HLR, divided into real users and virtual, it always becomes more difficult as the number of users and / or the HLR. The situation may get worse due to to, for example, the introduction of an additional network index.

By offering the desired phone number the fact that the total space for phone numbers available for activation is already organized in the MSC and distributed in the existing HLR. They contribute to this HLR divisions: with the launch of a new HLR must be assigned to it, telephone numbers and IMSI zones for that users can activate in this new HLR.

The associations described above characterize the implementation of the HLR as well as the allocation of telephone numbers and the numbering design of the center of Voicemail service (VMSC). It does not only derive a immense design cost, but also a high propensity to mistakes. In addition, it is also a waste of the HLR capacity.

Considerations similar to those that have been performed in relation to the HLR can also be performed by others network elements with user specific data. Just like it stored in the HLR the user data for GSM services, in the service control point (SCP) are deposited for example the user data for the intelligent network service of a Username.

In the GSM 03.02 standard (ETS 300 522) entitled "European Digital Cellular Telecommunications System (phase 2); network architecture "of the European Standardization Institute Telecommunications (ETSI) describes the so-called "network architecture" of the global communications system "Global System for Mobile Communications" (GSM) phones and with This is the digital cellular telecommunications system. GSM standard 03.04 (ETS 300 524) refers to "Telecommunications System European digital cell phone (phase 2); signaling requirements concerning the routing of calls to mobile subscribers. " document also refers to standards of the ETSI institute.

The GSM 09.02 (ETS 300 599) standard entitled "European Digital Cellular Telecommunications System (phase 2); specification of the mobile application part (MAP) ", which it also comes from the ETSI, it also belongs to the state of the technique. GSM standard 03.12 (ETS 300 530) refers to "System of European digital cellular telecommunications (phase 2); position registration procedures ", which also comes from ETSI The abbreviations and designations used come from these rules.

From DE 195 15 558 C1 it is known previously a procedure for establishing a connection  of call for calls to a radiotelephony user, in which, in the case of receiving a stay inquiry (SRI), a Central user database (HLR) checks on the mobile network local radiotelephony user if the device switching (GMSC1) requestor can support the spectrum of total service In case of a negative test result, send a request (PRN) in which the transmission contains additional information (RRI) and the user's phone number of radiotelephony (MSISDN) of the radiotelephony user who has been called. The transmission is sent to a user database peripheral (VRL 2) that belongs to a switching station mobile (GMSC2) that supports the service spectrum and that is intended for receiving incoming calls. Both information is stored in the user database peripheral (VLR2) that forwards a mobility number (MSRN) as request response (PRN) with a reference to the information stored As soon as a message (IAM) is received that activates the establishment of the call connection with the number of mobility (MSRN) that refers to additional information (RRI) in the local mobile radiotelephony network, mobile switching station (GMSC2) directs a second stay query (SRI) with the number of the radiotelephony user's telephone stored to the base of Central user data. With the mobility number already established in the new stay consultation, the station Mobile switching establishes the call connection. In this way a user can also, according to this procedure, whatever the network in which you are, use your specific services. The choice of the systems in which the connection is established is performs with the help of the requested service / spectrum of services and not based on the individual user, identified for example by your IMSI.

From WO 98/44640 A the sending short messages from a packet radio network (GPRS) It supports mobility. It is not recognized how it is chosen or find the HLR or the SMSC through the procedure and how you can routing to those network elements / systems. The procedure describes, among other things, how they can be sent and receive SMS from the packet data networks described by adding corresponding parameters in the messages signaling and in the HLR.

From WO 98/28920 it is known previously the transmission of short messages (SMS) in networks Smart (RI) when the caller or caller an IN service corresponds and an IN support is required for the SMS respective. However, the document does not describe any functionality on how the SMSC or SCP can be located responsable. Rather with the previously known procedure you should enable, among other things, the sending of SMS in a plan of private numbering (PNP) in which with the short message sent you establishes that an IN service is required for that SMS then transforms abbreviated dialing into long dialing.

objective

The invention is based on the objective of refine a prior art procedure established generic type in which, in at least one network of telecommunications according to the GSM standard, decoupling occurs  of the HLR design of phone number assignments and SIM card calls as a decoupling of the creation of MSISDN / IMSI distribution system data increasing the network quality by omitting user entries virtual

Otherwise, the invention is based on the aim of expanding this mode of individual and flexible way proceed to all elements related to specific data of user, such as HLR, AUC, EIR, VMSC, SMSC and SCP.

Solution

The objective is solved by characteristics reproduced in claim 1.

Other configurations of the invention

Other configurations of the invention are mentioned in claims 2 to 12.

Some advantages

As a new network element, the registration of network addresses configured as a router in a network of telecommunications, for example in a radiotelephony network, has first of all the objective of allowing an individual association of telecommunications users, for example users of mobile radiotelephony, to the network elements in question, by example to the HLR. This eliminates the formation of blocks. of phone numbers needed so far and their distribution, by example in the HLR, since this is compensated by the NAR.

By avoiding HLR entries in principle virtual, representing a frequent source of failures in the network effective as well as in the user activation environment, it Get an increase in quality.

       \ newpage
    

By using the procedure according to the invention is achieved through the NAR a saving of network elements, for example new HLRs, through better use of the capacity of existing network elements. In this way, the procedure according to the invention becomes profitable in a short time to despite the investment that derives from the use of the NAR. Other savings are derived from the scope of numbering design and administration  of phone numbers as well as the distribution of SIM cards, which can be simplified essentially with the NAR, and therefore It can become more efficient and economical.

With the NAR there is no incompatibility with the services, network elements and functions existing in a telecommunications network

Depending on the strategy for the network of existing telecommunications can be used the NAR mainly also for other applications, if any future, such as by example the realization of mobile number portability "Mobile Number Portability "(MNP).

Since the NAR is a routing device, Your software adapts to the respective requirements.

The task of a NAR therefore consists of determine the network element, for example an HLR, suitable for a message, so that the message can be transmitted where need, for example to SCP, SMSC, HLR, AUC, EIR, VMSC, ABC, MSC / VLR.

The NAR is therefore integrated into a GSM network existing that expands on network elements of the smart grid (RI). In addition to the traditional GSM and IN network elements must take into account the network elements for value services added, such as the short message service and the answering machine automatic.

There is no direct signaling relationship between all network elements.

The NAR as an effective network element of a administration system interface (AdC)

The NAR is incorporated as a network element directly, for example, in the establishment phase of the call on mobile termination calls "Mobile Terminating Calls "(MTC). This results in special requirements on the performance, to lengthen for example settling times of the call in MTC as little as possible.

In the signaling network, the NAR can be used as a duplicate core network element.

Since the NAR is not used in the network of switching but in the signaling network, neither addresses No transmission channel through the NAR. Nor does it appear for So much no formation of transmission channel loops.

Depending on the field of application used, by example routing to HLR or optimized VMSC routing, the NAR therefore has the objective of,

to)

                          determine a network element and forward to same the corresponding message (for example information of MAP sending routing to the HLR) or

b)

                         determine a network element address and return it as routing information to the system query (for example, INAP: initial DP + connection), so that the Consultation system itself can transmit the message.

As mentioned, the message flow must be configured so that the NAR performance is seen damaged as little as possible.

The addressing in the network elements Individuals are performed as follows:

Addressing based on the IMSI of Username:

one: VLR: MTP: DCP = SPAR of the NAR, OPC = SPC of the NAR VLR SCCP: called subscriber number = "IMSI" (E.214; E.212) subscriber number calling = VLR address (E.164)

In the VLR the global title analysis "Global Title Analysis "is configured in such a way that it is always taken the NAR SCP as DPC.

2: NAR: MTP: DPC = SPL of the HLR, OPC = SPC of the NAR SCCP: called subscriber number = "IMSI" (E.214; or E.212) subscriber number that flame = VLR address (E.164)

A title translation is done in the NAR global "Global Title Translation" which results in SPC of the HLR, which is used as a new DCP.

3: HLR: MTP: DCP = SPC of the VLR, OPC = SPC of the Hlr SCCP: called subscriber number = VLR address (E.164) subscriber number that flame = HLR address (E.164)

These addressing mechanisms are comparable with the existing mechanisms in the networks of GSM mobile radiotelephony.

Addressing based on the MSISDN of the Username:

one: VLR: MTP: DCP = SPAR of the NAR, OPC = SPC of the NAR VLR SCCP: called subscriber number = address of MS-ISDN (E.164) subscriber number that flame = VLR address (E.164)

In the VLR the global title analysis "Global Title Analysis "is configured in such a way that it is always taken the NAR SCP as DPC.

2: NAR: MTP: DPC = SPL of the HLR, OPC = SPC of the NAR SCCP: called subscriber number = MSISDN (E.164) subscriber number that flame = VLR address (E.164)

A title translation is done in the NAR global "Global Title Translation" which results in SPC of the HLR, which is used as a new DCP.

3: HLR: MTP: DCP = SPC of the VLR, OPC = SPC of the Hlr SCCP: called subscriber number = VLR address (E.164) subscriber number that flame = HLR address (E.164)

Alternatively to this, there is also the possibility of decoding messages in the NAR except the layer of application and then, with the help of the information obtained there (IMSI or MSISDN) perform subsequent routing.

Since the NAR, as the only network element effective, it still contains the association of in which network element physical user-specific data are found, for example in which physical HLR is the user data set of a specific user, requirements must be demanded from the NAR correspondingly high safety against breakdowns and reliability If no other NAR is available, this corresponds to a breakdown of all network elements in question, for example all HLRs in a conventional GSM network. In this case you can no longer having a successful MTC, however, MOCs are still possible. The availability of value-added services and the management of Mobility Management mobility are impaired considerably. For these reasons, the network structure must provide largely additional security. Therefore the use of duplicate systems in the network configuration also has meaning in the NAR.

If the procedure is considered according to the invention in relation to the HLR design, occurs

-

         the elimination of the association of IMSI / MSISDN zones with the Hlr

-

         virtual user entries are avoided

Thanks to this you get:

-

         decoupling the HLR design of number assignments from phone and SIM card production

-

         decoupling the representation of system data in the MSC of the MSISDN / IMSI distribution

-

         increased network quality through the absence of users virtual frequently affected by failures.

By introducing the NAR it is therefore given a modification of the routing principles in a network of telecommunications, for example a mobile radiotelephony network, because there is an individual user assignment of, for example, MSISDN / IMSI to the HLR. The database with the assignment is established in the NAR and must be included, correspondingly, in the queries in the HLR.

Mobility management

By subscribing to the telecommunications network in issue, for example for a mobile radiotelephony network, after the change of place of stay (VLR zone) or a new connection of the mobile communicates the new place of stay to the HLR so that, given In this case, the corresponding data can be updated. User identification is done through the IMSI. In the response, the HLR sends its network address to the VLR. In this At this time, the VLR knows the user's HLR address. With the help of this network address sends all other messages of the VLR directly to the HLR. (MAP: Status update "Update-Location"; IMSI; VLR \ rightarrow HLR)

Call control

During a call to a mobile user (MTC), the MSC gateway on the HLR asks for the current place of stay of the user called. The query occurs with the help of the number User Phone (MSISDN). (MAP: Send information from routing "Send-Routing-Information"; MSISDN; GMSC → HLR)

Short message

In the case of a short message that should Refer to a mobile user, the Message Service Center shorts (SMSC) in the HLR you must find out the place of stay of the user called. The NAR must also determine with help from the MSISDN to which HLR the message should be transmitted, sending routing information for short message "Send-Routing-Information-For-SM". If the target user cannot be located (for example if he has mobile off), the SMSC can ask in the HLR for information on the new accessibility of the user to re-send the short message (MAP: sending routing information for short message "Send-Routing-Information-For-SM";  MSISDN; SMSC \ High HLR) (MAP: standby adjustment data for message `` Set-Messaje-Waiting Data; MSISDN; SMSC → HLR)

Value added services

All actions performed for value-added services from the VLR towards the HLR, not They need no additional function in the NAR. The messages corresponding are routed from the VLR with the help of the HLR network address stored for the respective user at Corresponding HLR.

All value-added services that are perform from other network elements than the VLR, require that the NAR transmit the complementary service operation "Supplementary Service Operation" to the "correct" HLR, since that the other network elements do not know the network address of the HLR for a given user. For example, a service complementary can be pushed, for example, also by a VMSC

Through, for example, a service center Voicemail (VMSC), administration of value-added services by the user. For this it is necessary a MAP interface between the VMSC and the HLR. Since the VMSC does not Know the HLR network address for the user who processes your value-added service, the NAR must transmit the MAP message in the HLR with the help of IMSI.

Instead of from a VMSC, a equivalent embodiment, by way of example, also through a interactive voice response platform "Interactive Voice Response "(IVR).

Authentication Center (Auc)

In a mobile radiotelephony network you can also Integrate in each HLR the function of the AuC for the sets of User data stored in this HLR. For the realization of the authentication, the VLR finds out the necessary parameters in Auc. Since at the time of the user's subscription on the network The HLR network address in the VLR is not yet known, the NAR must transmit the MAP message for the authentication in the HLR / AuC with the help of IMSI.

(MAPv1: shipping parameters "Send-Parameters"; IMSI; VLR \ rightarrow HLR / AuC)

(MAPv2: Send Authentication Information "Send-Authentication-Info"; IMSI; VLR? HLR / AuC)

SIM card processing

There are situations where a Exchange of an existing user's SIM card; for example, in case of a defective SIM card or for the introduction of a new service At the same time, these users want to keep their Old phone number That means that with an MSISDN that it remains the same, a new IMSI is awarded to the user. The NAR with the possibility of flexible allocation of MSISDN and IMSI to user and to the HRL, considerably reduces the costs of administration associated with a SIM card exchange (the IMSI allocation to the HLR should be maintained) to avoid entries from virtual users A SIM card exchange takes place Normally in large numbers. Similarly, for the introduction of a new massive service that requires new SIM cards, the card SIM must be changed and managed accordingly in Many users The expected proportion of user entries virtual that will appear for it is considerable.

International roaming (ability to mobile position indication)

Nor do they derive from call control, in International roaming case, special requirements in the NAR.

Data Protection

No user data is stored in the NAR as, for example, complementary services, diversion destinations of Call or similar. The user profile is maintained in the HLR. In the NAR only deposits routing data, that is the information on which network element the data of Username. Therefore, data protection is not derived No special requirement in the NAR.

Smart Network (RI)

As in the HLR, the data of user for GSM services, at the service control point (SCP) user data is deposited for the IN services of a Username. If there are several SCPs in the network, it is also set to this case for the NAR the objective of discovering in which SCP are Store the data for a specific user. However, Therefore, two types of basic services must be distinguished: individual user services and network level services.

Individual user services

In individual user services, for the correct performance of the IN service is necessary that the data corresponding user names are available during the time of execution. This user-specific data is stored in the SCP. Therefore it may now be an objective of the NAR to determine which SCP should transfer service control.

(INAP: initial DP, service key "service key ", calling subscriber number (MSISDN), IMSI, IMEI) for services that originate.

(INAP: initial DP, service key "service key ", called subscriber number (MSISDN), IMSI, IMEI) for terminating services, such as call filtering from termination "terminating call screening".

Network level services

For network level services they are not important individual user data However, it must be determined the SCP on which the service logic is implemented. The critery of routing for the choice of the SCP is not in this case the User phone number but your service key.

(INAP: initial DP, service key)

Portability of local number (LNP)

When a client in the fixed network changes from network operator, you can keep your phone number. The net actual target of the called user can be determined already in the call establishment phase through the network original (call inquiry "On-Call-Query"). In this case, in the original network a database is asked where they are Registered users transferred. Due to the high load dynamic expected by database queries, it impose special requirements on the performance capacity of the database. This LNP database could be done in the NAR

Portability of the mobile number (MNP)

Currently, NMP normalization is being trying in the ETSI. It stands out because you can choose between two implementation variants. A variant is based on the protocol MAP and the other in the INAP protocol. Once the standardization in the ETSI requirements must be developed in the NAR for call control, mobility management and treatment of complementary services (for example, for CCBS).

Optimized voicemail routing

For capacity reasons, several are used Voicemail service centers in the radiotelephony network mobile. The distribution of users in the system is oriented currently to the phone number. A cheaper distribution can be achieved if the location of the mail system of voice as close as possible to the most frequent place of stay of the Username. This means an individual assignment of the user in instead of a block assignment. This imposes requirements in the NAR comparable with those of the HLR.

Team Identity Registration (EIR)

The NAR can decide, where appropriate, with the help of IMEI, to what EIR the query should be sent. Currently, in the MSC Only the address of an EIR can be entered. No one is planned routing distribution according to IMEI blocks. This it would mean that in each EIR all IMEI must be stored, what which is not desirable from the point of view of the consistency of the data. Routing to the respective EIR could Distributed regionally. With a NAR in the network, the routing with the help of IMEI, so that in each EIR only a portion of the IMEI registered as stolen must be deposited. A possible inconsistency of the data can be excluded from this mode.

(MAP: check IMEI, IMEI)

Users Management

As an extension of the functionality of the NAR, must react as a single "individual HLR" to ABC. All activations / modifications are now sent only to the NAR and it then chooses a suitable HLR and forwards the message to the HLR physical.

It should be especially highlighted again the utility of using the NAR as an HLR router. By means of the introduction of the NAR can be solved efficiently many tasks in the aforementioned fields. The savings in Costs that result from this are offset against additional expenses resulting from the introduction of a new network element, the NAR In addition to cost savings, thanks to a rate of optimized use of the respective network elements, by For example, existing HLR saves in future investments for such network elements, for example in the HLR.
